Skin and Musculoskeletal Flashcards
Skin is waterproof, protective, and adaptive. Other functions?
Protection from environment, perception, temp regulation, identification, communication, wound repair, absorption and excretion, production of vit D
Skin in infants?
Temp regulation, hot and cold. Eccrine sweat glands are not effective initially. Subcutaneous tissue. Decrease in pigmentation.
Skin in children?
Epidermis thickens, darkens, and becomes lubricated. Hair growth accelerates.
Skin in adolescents?
Secretions from apocrine sweats glands, sebaceous glands increase. Subcutaneous fat deposits increase. Secondary sex characteristics: areola, pubic and axillary hair, facial hair on men
What happens to skin in the aging adult?
Loses elasticity, skin folds and sags. Decrease in number and function of sweat and sebaceous glands. Discoloration due to increasing capillary fragility: senile purpura. Cell replacement is slower and wound healing is delayed. Functioning melanocytes decrease, leading to gray fine hair.
Subjective info for the skin?
Previous history of disease, change in moles and pigmentation, excessive dryness or moisture, pruritus excessive bruising, rash or lesions, medications environmental or occupational hazards, self-care behaviors.
How do you inspect the skin?
General pigmentation, freckles, moles, birthmarks. Widespread color change, noting any color changes. Texture, turgor
If lesions are present, what should be noted?
Color, elevation, pattern or shape, size, location and distribution on body, any exudate. Use a Wood’s light.
Shapes and configurations of lesions?
Annular or circular, confluent, discrete, grouped, serpiginious, grate, target, linear, zosteriform
ABCDE skin assessment?
Asymmetry Border Color mixture or change Diameter greater than 6mm Elevation, evolution, enlargement
The outer, highly differentiated layer of skin?
The inner, supportive layer made mostly of collagen?
The layer beneath?
Epidermis
Dermis
Subcutaneous
From the basal cell layer of skin, new cells migrate up and flatten into what outer layer? It consists of dead keratinized cells that are interwoven and tightly packed.
Horny cell layer
The epidermis is replaced every four weeks.
When does cyanosis occur?
It indicates hypoxemia and occur with shock, cardiac arrest, heart failure, chronic bronchitis, and congenital heart disease.
What does the pallor of shock often present with?
Rapid pulse rate, oliguria, apprehension, and restlessness.
Solid raised lesion that has distinct borders and is less than 1 cm in diameter.
Papule. May have a variety of shapes in profile (domed, flat-topped, umbilicated) and may be associated with secondary features such as crusts or scales.
Solid, raised, flat-topped lesion greater than 1 cm. in diameter. It is analogous to the geological formation, the plateau.
Plaque
Raised lesions less than 1 cm that are filled with clear fluid
Vesicle
Circumscribed clear- fluid-filled lesions that are greater than 1 cm. in diameter.
Bullae
